Updating sansa firmware
With a more recent Sansa firmware San Disk changed the TEA encryption key (and named their firmware file " The Rhapsody version of the Sansa e200 series uses yet another key that was successfully extracted on February 23, 2007. They name the firmware file pp5022.mi4 (note the lower case).
The Rhapsody BL does not allow a "dummy" DSA signed mi4 file to get loaded.
Different HW revisions doing it differently perhaps?
Vendor: San Disk Model: Sansa e250 Rev: Type: Direct-Access ANSI SCSI revision: 02 SCSI device sda: 32769 512-byte hdwr sectors (17 MB) sda: assuming Write Enabled sda: assuming drive cache: write through sda: unknown partition table ...
At work we build a lot of open source software using mostly open source software. I hoped the Sansa Clip Zip could handle the music, since after all it is a dedicated device.
There are, however, cases where closed software is more expedient… On the other end of the spectrum, there’s the Sansa Clip Zip. ) But I’m tired of loading and unloading stuff on the Shuffle, due to the lack of capacity. I loaded most of my music in i Tunes onto the micro SD card, and put it in an Android phone. It flashed low memory when booted with the micro SD card. I bought it thinking, “So I can get this for less than and it has a micro SD slot.
so there's no partitions but I had to mount /dev/sda instead of /dev/sda1.
On the surface, their firmware does look different from Rockbox. Who cares how intuitive it is if you would have to set aside a few days of your life just to figure out which half of your i Tunes music collection it can load?Then I noticed the device occasionally freezing, seemingly when coming across certain music files. Power button would not work, requiring a long select power key press to restart. This is a case where the decision has gone in favor of proprietary software even though the free software alternative actually works better! A bit overpriced for 2 GB, but good when running or skiing, nice integration with i Tunes, and Apple has replaced them without comment when they break down. Or I can spend hundreds to get enough capacity on a fragile device that is probably no better for what I want to do.” The Sansa Clip Zip is a dedicated device, all right.Yet with the original firmware it also chokes on the micro SD card full of music. both full of music and both causing the same symptoms on the Android phone and also on the Sansa Clip Zip with original firmware.
"pre-bootloader" - in which the Sansa appears as a "Portal Player USB Device." - e200tool 0.0.6 and later can (hopefully) access the device in this mode.
